Chocolate Sprinkle Sheet Cake Recipes

Steps:

• Cake: Preheat oven to 350°F. Brush a 9-by-13-inch or 8-by-12-inch baking pan with butter. Line with parchment, leaving a 2-inch overhang on long sides. Butter parchment.
• Whisk together flour, cocoa, baking powder, and salt. Combine eggs and granulated sugar in the bowl of a mixer fitted with the whisk attachment. Beat on high speed until thick and pale, about 4 minutes. Add flour mixture; beat just to combine. Add butter and vanilla; beat to combine. Add sour cream; beat until smooth.
• Scrape batter into prepared pan, smoothing top with a spatula. Bake until top springs back when lightly touched and a tester inserted in center comes out clean, 30 to 35 minutes (for 9-by-13-inch) or about 40 minutes (for 8-by-12).
• Let cool in pan on a wire rack 10 minutes. Using parchment overhangs, lift out of pan and let cool completely on rack. (Cake can be made to this point and stored at room temperature, wrapped in plastic, up to 1 day.)
• Frosting: Beat together butter, confectioners' sugar, cocoa, and milk on medium-high speed until light and fluffy, about 5 minutes. Spread over top of cake. Decorate with sprinkles. Frosted cake is best the day it's assembled, but can be refrigerated, wrapped in plastic, up to 1 day. Return to room temperature before serving.

Steps:

• Lightly grease a 9-by-13-inch pan with nonstick spray. Heat the oven to 350 degrees.
• Make the cake: In the bowl of an electric mixer fitted with the paddle attachment, cream the butter and sugar on medium speed until light and fluffy, 4 to 5 minutes. Beat in the eggs one at a time, then the egg yolk, scraping the sides of the bowl after each addition. Mix on medium speed until fully incorporated, about 1 minute. Add the vanilla extract and mix to combine, 15 to 30 seconds.
• In a medium bowl, whisk the flour, baking powder, baking soda and salt to combine. Add about 1/3 of the flour mixture to the mixer and mix on low speed until incorporated, about 30 seconds. Add about half the milk and mix on low speed until incorporated, about 15 seconds more. Repeat with another batch of flour mixture, the remaining milk, then the remaining flour mixture until fully incorporated.
• Transfer the batter to the prepared pan and spread in an even layer. Bake until a toothpick inserted into the center comes out clean and the cake is golden and separating from the pan at the edges, 30 to 35 minutes. Cool completely.
• Meanwhile, make the frosting: Add the butter to the bowl of an electric mixer fitted with the paddle attachment and beat on medium speed until light and fluffy, 3 to 4 minutes. Remove the bowl from the electric mixer, and sift the confectioners' sugar and cocoa into the bowl with the butter. Stir with a spatula a few times to incorporate slightly. Return the bowl to the mixer and beat on medium speed until smooth and uniform in color, 1 to 2 minutes. Add the sour cream and melted chocolate and mix on low speed until combined, about 30 seconds. Add the vanilla and salt and mix to combine.
• Spread the frosting on the cooled cake in an even layer. Garnish with sprinkles, if desired.

Steps:

• For the yellow cake: Preheat the oven to 350 degrees F. Line a 9-inch-by-13-inch (quarter-sheet) pan with parchment paper, then spray with nonstick baking spray.
• Place 2 metal flower nails in the center of the pan, flat-side down, a few inches apart. Beat the butter and granulated sugar in the bowl of a stand mixer fitted with the whisk attachment on medium-high speed to incorporate air into mixture, about 2 minutes. Mix in the eggs on low speed, two at a time. Scrape down the sides of the bowl as needed with a rubber spatula.
• Whisk together the cake flour, baking powder and salt in a separate bowl. Add a third of the dry ingredients to the butter mixture and mix on low speed. Mix in half of the buttermilk on low speed. Repeat this process, finishing with the last third of the dry ingredients. Mix in the vanilla extract and oil, then pour the batter into the prepared pan. Reposition the flower nails so that they're evenly spaced in the pan. Tap the pan on the counter to remove any air bubbles, then bake until a toothpick inserted in the center comes out clean or with a few moist crumbs, 25 to 26 minutes.
• Allow the cake to cool in the pan for about 15 minutes, then carefully flip it onto a cooling rack to finish cooling.
• For the dark chocolate buttercream: Beat the butter in a stand mixer fitted with the paddle attachment on medium speed until smooth, about 30 seconds. Turn the mixer to low speed and add the cocoa, then mix until the cocoa is fully incorporated and no clumps remain. Slowly add the powdered sugar, 1 cup at a time, alternating with small splashes of cream. Mix in the melted dark chocolate, then the salt. Beat until the ingredients are fully incorporated and the desired consistency is reached. If the frosting is too thick, add an extra tablespoon of heavy cream. If it's too thin, add another 1/2 cup powdered sugar. Stir by hand with a rubber spatula for a couple minutes to make the frosting super smooth.
• Remove the flower nails from the cake. Spread an even layer of chocolate buttercream on top of the cake, making swirls with an offset spatula. Top with rainbow sprinkles.

Steps:

• For the cake: Preheat the oven to 350 degrees F.
• In a large bowl, combine the flour, sugar and salt. Stir together and set aside.
• In another bowl, mix the buttermilk, baking soda, vanilla and eggs. Mix with a fork and set aside.
• In a medium saucepan, melt the butter and add the cocoa. Whisk together to combine. Meanwhile, bring 1 cup water to a boil. When the butter is melted, pour the boiling water in the pan. Allow to bubble for a moment, then turn off the heat. Pour the chocolate mixture into the flour mixture. Stir together for a moment to cool the chocolate, then pour in the egg mixture. Stir together until smooth, then pour into an ungreased jelly roll pan (or rimmed baking sheet) and bake for 20 minutes.
• While the cake is baking, make the icing: Melt the butter in a saucepan over medium-low heat. Add the cocoa powder and stir until smooth. Add the milk, vanilla and powdered sugar. Stir together. Dump in the pecans and stir until well combined.
• Immediately after removing the cake from the oven, pour the warm icing over the top. You'll want to avoid doing much spreading, so try to distribute it evenly as you pour.
